问添加为带有UIImageView的UIView中的子视图的clipsToBounds不起作用

EN

let rectangleView = UIView(frame: CGRect(x: x, y: y, width: width, height: height))
rectangleView.isUserInteractionEnabled = false

if let texturesUrl = layout.Url, let url = texturesUrl.isValidURL() ? URL(string: texturesUrl) : URL(string: String(format: AppManager.shared.baseTexturesUrl, texturesUrl)) {
     let widthLimit = scale * CGFloat(layout.Width ?? 0)
     let heightLimit = scale * CGFloat(layout.Height ?? 0)
     let widthStep = scale * CGFloat(layout.TileWidth ?? layout.Width ?? 0)
     let heightStep = scale * CGFloat(layout.TileHeight ?? layout.Height ?? 0)

     var locY = CGFloat(0)
     let size = CGSize(width: widthStep, height: heightStep)

     if widthLimit > 0, heightLimit > 0 {
          while locY < heightLimit {
              var locX = CGFloat(0)
                  while locX < widthLimit {
                      let imageView = UIImageView()
                      rectangleView.addSubview(imageView)
                      imageView.contentMode = .scaleAspectFill
                      imageView.translatesAutoresizingMaskIntoConstraints = false
                      imageView.clipsToBounds = true
                      imageView.isUserInteractionEnabled = false
                      imageView.anchor(top: rectangleView.topAnchor, leading: rectangleView.leadingAnchor, bottom: nil, trailing: nil, padding: UIEdgeInsets(top: locY, left: locX, bottom: 0, right: 0), size: size)
                      imageView.setImage(with: url, size: size)
                      locX += widthStep
                  }
                  locY += heightStep
              }
          }
     }
